Fabspeed Supersport X-Pipe for Porsche 991 Turbo & Turbo S (2013–2019)

Description

Fabspeed’s Supersport X-Pipe Exhaust System replaces the heavy and restrictive factory rear mufflers and catalytic converters with a flowing 70 mm (2.75″) stainless X-pipe, 200-cell HJS sport cats, and quad resonated tips. This free-flowing design unlocks +25 whp and +31 lb-ft of torque while dropping around 5 lbs of weight, giving your 991 Turbo a more aggressive sound and sharper throttle feel. Built from CNC-mandrel 14–16 ga T304L stainless steel, it’s a durable, bolt-on solution engineered for performance and longevity — backed by Fabspeed’s lifetime warranty.
